INTRODUCTION

FIRE SAFETY TIPS

Follow safety rules and prevent hazardous situations: 1) Use smoking

materials properly. Never smoke in bed. 2) Keep matches or lighters

away from children; 3) Store flammable materials in proper containers;

4) Keep electrical appliances in good condition and don’t overload

electrical circuits; 5) Keep stoves, barbecue grills, fireplaces and

chimneys grease- and debris-free; 6) Never leave anything cooking

on the stove unattended; 7) Keep portable heaters and open flames,

like candles, away from flammable materials; 8) Don’t let rubbish

accumulate.

Keep alarms clean, and test them weekly. Replace alarms immediately

if they are not working properly. Smoke Alarms that do not work cannot

alert you to a fire. Keep at least one working fire extinguisher on every

floor, and an additional one in the kitchen. Have fire escape ladders or

other reliable means of escape from an upper floor in case stairs are

blocked.

BASIC SAFETY INFORMATION

• Dangers, Warnings, and Cautions alert you to important

operating instructions or to potentially hazardous situations.

Pay special attention to these items.

• This Smoke/CO Alarm is approved for use in single-family

residences. It is NOT designed for marine or RV use.

•

This combination Smoke/Carbon Monoxide Alarm has two

separate alarms. The CO Alarm is not designed to detect fire

or any other gas. It will only indicate the presence of carbon

monoxide gas at the sensor. Carbon monoxide gas may be

present in other areas. The Smoke Alarm will only indicate

the presence of smoke that reaches the sensor. The Smoke

Alarm is not designed to sense gas, heat or flames.

• This Smoke/CO Alarm cannot operate without working

batteries. Removing the batteries for any reason, or failing

to replace the batteries at the end of their service life,

removes your protection.

• NEVER ignore any alarm. See “If Your Smoke/CO Alarm

Sounds” for more information on how to respond to an

alarm. Failure to respond can result in injury or death.

• The Silence Features are for your convenience only and will

not correct a problem. See “Using the Silence Features” for

details. Always check your home for a potential problem

after any alarm. Failure to do so can result in injury or death.

• Test this Smoke/CO Alarm once a week. If the Alarm ever fails

to test correctly, have it replaced immediately! If the Alarm is

not working properly, it cannot alert you to a problem.

• This product is intended for use in ordinary indoor locations

of family living units. It is not designed to measure CO

levels in compliance with Occupational Safety and Health

Administration (OSHA) commercial or industrial standards.

Individuals with medical conditions that may make them

more sensitive to carbon monoxide may consider using

warning devices which provide audible and visual signals

for carbon monoxide concentrations under 30 ppm. For

additional information on carbon monoxide and your medical

condition contact your physician.

Features:

• Separate sensors to

detect smoke and CO;

the two alarm systems

work independently

• Powered by two “AA”

batteries

• Access door for easy

battery replacement

All First Alert

® Smoke Alarms conform to regulatory requirements,

including UL217 and are designed to detect particles of combus-

tion. Smoke particles of varying number and size are produced

in all fires.

Ionization technology is generally more sensitive than photo-

electric technology at detecting small particles, which tend

to be produced in greater amounts by flaming fires, which

consume combustible materials rapidly and spread quickly.

Sources of these fires may include paper burning in a wastebasket, or

a grease fire in the kitchen.

Photoelectric technology is generally more sensitive than

ionization technology at detecting large particles, which tend

to be produced in greater amounts by smoldering fires, which

may smolder for hours before bursting into flame. Sources of

these fires may include cigarettes burning in couches or bedding.

For maximum protection, use both types of Smoke Alarms on

each level and in every bedroom of your home.

RECOMMENDED PLACEMENT

• When installing on the wall, the top edge of Smoke Alarms should

be placed between 4 inches (102 mm) and 12 inches (305 mm)

from the wall/ceiling line.

• When installing on the ceiling, place the alarm as close to the

center as possible.

• In either case, install at least 4 inches (102 mm) from where the

wall and ceiling meet. See “Avoiding Dead Air Spaces” for more

information.

NOTE: For any location, make sure no door or other obstruction could

keep carbon monoxide or smoke from reaching the Alarm.

Installing Smoke/CO Alarms in Mobile Homes

For minimum security install one Smoke/CO Alarm as close to each

sleeping area as possible. For more security, put one unit in each room.

Many older mobile homes (especially those built before 1978) have little

or no insulation. If your mobile home is not well insulated, or if you are

unsure of the amount of insulation, it is important to install units on

inside walls only.

WHERE THIS ALARM SHOULD NOT BE INSTALLED

Do NOT locate this Smoke/CO Alarm:

• In garages, furnace rooms, crawl spaces and unfinished attics.

Avoid extremely dusty, dirty or greasy areas.

• Where combustion particles are produced. Combustion particles

form when something burns. Areas to avoid include poorly ventilated

kitchens, garages, and furnace rooms. Keep units at least 20 feet

(6 meters) from the sources of combustion particles (stove, furnace,

water heater, space heater) if possible. In areas where a 20-foot

(6 meter) distance is not possible – in modular, mobile, or smaller

homes, for example – it is recommended the Smoke Alarm be

placed as far from these fuel-burning sources as possible. The

placement recommendations are intended to keep these Alarms at

a reasonable distance from a fuel-burning source, and thus reduce

“unwanted” alarms. Unwanted alarms can occur if a Smoke Alarm

is placed directly next to a fuel-burning source. Ventilate these

areas as much as possible.

• Within 5 feet (1.5 meters) of any cooking appliance. In air streams

near kitchens. Air currents can draw cooking smoke into the smoke

sensor and cause unwanted alarms.

• In extremely humid areas. This Alarm should be at least 10 feet

(3 meters) from a shower, sauna, humidifier, vaporizer, dishwasher,

laundry room, utility room, or other source of high humidity.

• In direct sunlight.

• In turbulent air, like near ceiling fans or open windows. Blowing air

may prevent CO or smoke from reaching the sensors.

• In areas where temperature is colder than 40˚ F (4.4˚ C) or hotter

than 100˚F (37.8˚ C). These areas include non-airconditioned crawl

spaces, unfinished attics, uninsulated or poorly insulated ceilings,

porches, and garages.

• In insect infested areas. Insects can clog the openings to the

sensing chamber.

• Less than 12 inches (305 mm) away from fluorescent lights.

Electrical “noise” can interfere with the sensor.

• In “dead air” spaces. See “Avoiding Dead Air Spaces”.

AVOIDING DEAD AIR SPACES

“Dead air” spaces may prevent smoke from reaching the Smoke/CO

Alarm. To avoid dead air spaces, follow installation recommendations

below.

On ceilings, install Smoke/CO Alarms as close to the center of the

ceiling as possible. If this is not possible, install the Smoke/CO Alarm

at least 4 inches (102 mm) from the wall or corner.

For wall mounting (if allowed by building codes), the top edge of

Smoke/CO Alarms should be placed between 4 inches (102 mm) and

12 inches (305 mm) from the wall/ceiling line, below typical “dead air”

spaces.

On a peaked, gabled, or cathedral ceiling, install first Smoke/CO

Alarm within 3 feet (0.9 meters) of the peak of the ceiling, measured

horizontally. Additional Smoke/CO Alarms may be required depending

on the length, angle, etc. of the ceiling’s slope. Refer to NFPA 72 for

details on requirements for sloped or peaked ceilings.

INSTALLATION

WHERE TO INSTALL THIS ALARM

Minimum coverage for Smoke Alarms, as recommended by the

National Fire Protection Association (NFPA), is one Smoke Alarm

on every floor, in every sleeping area, and in every bedroom (See

“Regulatory Information For Smoke Alarms” for details on the NFPA

recommendations).

For CO Alarms, the National Fire Protection Association (NFPA)

recommends that a CO Alarm should be centrally located outside of

each separate sleeping area in the immediate vicinity of the bedrooms.

For added protection, install additional CO Alarms in each separate

bedroom, and on every level of your home.

NOTE: For added protection, install an additional Smoke/CO Alarm at

least 15 feet (4.6 meters) away from the furnace or fuel burning heat

source where possible. In smaller homes or in manufactured homes

where this distance cannot be maintained, install the Alarm as far away

as possible from the furnace or other fuel burning source. Installing the

Alarm closer than 15 feet (4.6 meters) will not harm the Alarm, but may

increase the frequency of unwanted alarms.

In general, install combination Smoke and Carbon Monoxide

Alarms:

• On every level of your home, including finished attics and

basements.

• Inside every bedroom, especially if people sleep with the door

partly or completely closed.

• In the hall near every sleeping area. If your home has multiple

sleeping areas, install a unit in each. If a hall is more than 40 feet

(12 meters) long, install a unit at each end.

• At the top of first-to-second floor stairs.

• At the bottom of the basement stairs.

• For additional coverage, install Alarms in all rooms, halls, and

storage areas, where temperatures normally remain between 40˚ F

and 100˚ F (4.4˚ C and 37.8˚ C).

HOW TO INSTALL THIS ALARM

This combination Smoke/CO Alarm was designed to be mounted

on the ceiling or wall. It is not a tabletop device. You must install this

device on the ceiling or wall as outlined below. Read “Where To Install

5 Battery door, install

batteries here

FOLLOW THESE SIMPLE STEPS:

1. Hold base firmly and twist the mounting bracket clockwise to

separate it from the base.

2. Hold the mounting bracket against

the ceiling (or wall) so the two

clusters of universal mounting holes

are aligned approximately at the

9:00 and 3:00 o’clock positions. See

image. Choose one of the

three sets of holes shown, A, B or

C (see image) and trace around one

of the sets. Be sure to choose a top

and bottom slot on opposite sides

so you can rotate the universal

mounting bracket into position later.

This will make it easier in the future

to remove the mounting bracket

without completely removing the

screws.

3. Put the unit where it won’t get covered with dust when you drill the

mounting holes.

4. Using a 3/16” (5 mm) drill bit, drill a hole through the center of the

oval outlines you traced.

5. Insert the plastic screw anchors (in the plastic bag with screws)

into the holes. Tap the screw anchors gently with a hammer, if

necessary, until they are flush with the ceiling or wall.

6. Install the screws but do not tighten completely. Attach the

mounting bracket by aligning the screws in the open portion of

the universal mounting slots and rotating the bracket into place.

Tighten the screws until they are snug to secure the bracket.

Do not over tighten.

7. Install the batteries (included). Open the battery door. Match the

terminals on the ends of each battery with the terminals on the

unit. Match “+” to “+” and “-” to “-.” Push the batteries in until they

snap securely and cannot be shaken loose. If the batteries are not

snapped in completely, the unit cannot receive battery power.

NOTE: After you install the batteries, the power indicator light may

flash. (If the unit alarms, the light will blink rapidly, and the horn will

repeatedly sound 3 beeps, pause, 3 beeps.)

8. Position the base of the Alarm over the mounting bracket and turn.

Turn the Alarm clockwise until the unit is in place.

9. Test the Alarm. See “Weekly Testing.”

WEEKLY TESTING

• NEVER use an open flame of any kind to test this unit. You

might accidentally damage or set fire to the unit or to your

home. The built-in test switch accurately tests the unit’s

operation as required by Underwriters Laboratories, Inc. (UL).

NEVER use vehicle exhaust! Exhaust may cause permanent

damage and voids your warranty.

• DO NOT stand close to the alarm when the horn is sounding.

Exposure at close range may be harmful to your hearing. When

testing, step away when horn starts sounding.

It is important to test this unit every week to make sure it is working

properly. Using the test button is the recommended way to test this

Smoke/CO Alarm.

You can test this Smoke/CO Alarm: Press and hold the Test/Silence

button 3-5 seconds until unit starts to alarm. During testing, you will

see and hear the following sequence:

• The will sound 3 beeps, pause, 3 beeps. The flashes Horn LED

Red.

• Next the will sound 4 beeps, pause, 4 beeps. TheHorn LED

flashes Red.

If the unit does not alarm, make sure the batteries are correctly

installed, and test again. If the unit still does not alarm, replace it

immediately.

IF THE SMOKE ALARM SOUNDS

RESPONDING TO AN ALARM

• If the unit alarms and you are not testing the unit, it is warning

you of a potentially dangerous situation that requires your

immediate attention. NEVER ignore any alarm. Ignoring the

alarm may result in injury or death.

• Never remove the batteries from a battery operated Smoke/CO

Alarm to stop an unwanted alarm (caused by cooking smoke,

etc.). Removing batteries disables the alarm so it cannot sense

smoke, and removes your protection. Instead open a window

or fan the smoke away from the unit. The alarm will reset

automatically.

• If the unit alarms get everyone out of the house immediately.

WHAT TO DO IN CASE OF FIRE

• Don’t panic; stay calm. Follow your family escape plan.

• Get out of the house as quickly as possible. Don’t stop to get

dressed or collect anything.

• Feel doors with the back of your hand before opening them.

If a door is cool, open it slowly. Don’t open a hot door. Keep

doors and windows closed, unless you must escape through

them.

• Cover your nose and mouth with a cloth (preferably damp).

Take short, shallow breaths.

• Meet at your planned meeting place outside your home, and

do a head count to make sure everybody got out safely.

• Call the Fire Department as soon as possible from outside.

Give your address, then your name.

• Never go back inside a burning building for any reason.

• Contact your Fire Department for ideas on making your home

safer.

Alarms have various limitations. See “General Limitations of

Smoke/CO Alarms” for details.

IF THE CO ALARM SOUNDS

Actuation of your CO Alarm indicates the presence of carbon

monoxide (CO) which can kill you. In other words, when your CO

Alarm sounds, you must not ignore it!

IF THE CO ALARM SIGNAL SOUNDS:

1. Press the Test/Silence button.

2. Call your emergency services, fire department or 911. Write down

the number of your local emergency service here:

_____________________________________________________________

3. Immediately move to fresh air—outdoors or by an open door or

window. Do a head count to check that all persons are accounted

for. Do not re-enter the premises, or move away from the open door

or window until the emergency services responder has arrived, the

premises have been aired out, and your CO Alarm remains in its

normal condition.

4. After following steps 1-3, if your CO Alarm reactivates within a

24-hour period, repeat steps 1-3 and call a qualified appliance

technician to investigate for sources of CO from fuel-burning

equipment and appliances, and inspect for proper operation of this

equipment. If problems are identified during this inspection have the

equipment serviced immediately. Note any combustion equipment

not inspected by the technician, and consult the manufacturers’

instructions, or contact the manufacturers directly, for more

information about CO safety and this equipment. Make sure that

motor vehicles are not, and have not, been operating in an attached

garage or adjacent to the residence. Write down the number of a

qualified appliance technician here:

_____________________________________________________________

NOTE: A qualified appliance technician is defined as “a person, firm,

corporation, or company that either in person or through a

representative, is engaged in and responsible for the installation,

testing, servicing, or replacement of heating, ventilation, air conditioning

(HVAC) equipment, combustion appliances and equipment, and/or gas

fireplaces or other decorative combustion equipment.”

“ALARM-MOVE TO FRESH AIR”

If you hear the CO alarm horn and the CO red light is flashing,

move everyone to a source of fresh air.

DO NOT remove the batteries!

REGULAR MAINTENANCE

This unit has been designed to be as maintenance free as possible, but

there are a few simple things you must do to keep it working properly.

• Test it at least once a week.

• Clean the Smoke/CO Alarm at least once a month; gently vacuum

the outside of the Smoke/CO Alarm using your household vacuum’s

soft brush attachment. A can of clean compressed air (sold at

computer or office supply stores) may also be used. Follow

manufacturer instructions for use. Test the Smoke/CO Alarm. Never

use water, cleaners or solvents since they may damage the unit.

• If the Smoke/CO Alarm becomes contaminated by excessive dirt,

dust and/or grime, and cannot be cleaned to avoid unwanted

alarms, replace the unit immediately.

• Relocate the unit if it sounds frequent unwanted alarms. See

“Where This Alarm Should Not Be Installed” for details.

Choosing a replacement battery:

Your Smoke/CO Alarm requires two standard AA batteries. The following

batteries are acceptable as replacements: Eveready Energizer E91 or

Duracell MN1500. These batteries are available at many local retail

stores.

• Always use the exact batteries specified by this User’s Manual.

DO NOT use rechargeable batteries. Clean the battery contacts

and also those of the device prior to battery installation. Install

batteries correctly with regard to polarity (+ and -).

• Please dispose of or recycle used batteries properly, following

any local regulations. Consult your local waste management

authority or recycling organization to find an electronics

recycling facility in your area. DO NOT DISPOSE OF BATTERIES

IN FIRE. BATTERIES MAY EXPLODE OR LEAK.

• Keep battery out of reach of children. In the event a battery is

swallowed, immediately contact your poison control center,

your physician, or the National Battery Ingestion hotline at

202-625-3333 as serious injury may occur.

Actual battery service life depends on the Smoke/CO Alarm and the

environment in which it is installed. All the batteries specified above

are acceptable replacement batteries for this unit. Regardless of the

manufacturer’s suggested battery life, you MUST replace the battery

immediately once the unit starts “chirping” (the “low battery warning”).

USING THE SILENCE FEATURES

Never remove the batteries to quiet an unwanted alarm. Removing

the batteries disables the alarm and removes your protection.

The Silence Feature is intended to temporarily silence the horn while

you identify and correct the problem. Do not use the Silence Feature

in emergency situations. It will not correct a CO problem or extinguish

a fire.

The Silence Feature can temporarily quiet an unwanted alarm for several

minutes. Press the Test/Silence button on the alarm cover for at least

3-5 seconds.

After the Test/Silence button is released, the Red LED blinks during the

silence mode.

SILENCING THE LOW BATTERY WARNING

This silence feature can temporarily quiet the low battery warning

“chirp” for up to 8 hours. Press the Test/Silence button on the alarm

cover.

Once the low battery warning “chirp” silence feature is activated, the

unit continues to flash the Green light once a minute for 8 hours. After

8 hours, the low battery “chirp” will resume. Replace the batteries as

soon as possible; this unit will not operate without battery power!

To deactivate this feature: Press the Test/Silence button again. The

unit will go into Test Mode and the low battery warning will resume

(LED flashes and unit sounds “chirp” once a minute).

SILENCING THE END OF LIFE SIGNAL

This silence feature can temporarily quiet the End of Life warning

“chirp” for up to 2 days. You can silence the End of Life warning “chirp”

by pressing the Test/Silence button. The horn will chirp, acknowledging

that the End of Life silence feature has been activated.

After approximately 2 days, the End of Life “chirp” will resume.

When the Smoke Alarm is

Silenced

When the CO Alarm is Silenced

The Smoke Alarm will remain

silent for up to 15 minutes, then

return to normal operation.

If the smoke has not cleared–or

continues to increase–the device

will go back into alarm.

The CO Alarm will remain silent

for up to 4 minutes.

After 4 minutes, if CO levels

remain potentially dangerous the

horn will start sounding again.

WHAT YOU NEED TO KNOW ABOUT CO

WHAT IS CO?

CO is an invisible, odorless, tasteless gas produced when fossil fuels

do not burn completely, or are exposed to heat (usually fire). Electrical

appliances typically do not produce CO.

These fuels include: Wood, coal, charcoal, oil, natural gas, gasoline,

kerosene, and propane.

Common appliances are often sources of CO. If they are not properly

maintained, are improperly ventilated, or malfunction, CO levels can

rise quickly. CO is a real danger now that homes are more energy

efficient. “Air-tight” homes with added insulation, sealed windows,

and other weatherproofing can “trap” CO inside.

SYMPTOMS OF CO POISONING

These symptoms are related to CO POISONING and should be

discussed with ALL household members.

Mild Exposure: Slight headache, nausea, vomiting, fatigue (“flu-like”

symptoms).

Medium Exposure: Throbbing headache, drowsiness, confusion, fast

heart rate.

Extreme Exposure: Convulsions, unconsciousness, heart and lung

failure. Exposure to Carbon Monoxide can cause brain damage, death.

This CO Alarm measures exposure to CO over time. It alarms if CO

levels are extremely high in a short period of time, or if CO levels reach

a certain minimum over a long period of time. The CO Alarm generally

sounds an alarm

before the onset of symptoms in average, healthy

adults. Why is this important?

Because you need to be warned of a

potential CO problem while you can still react in time. In many reported

cases of CO exposure, victims may be aware that they are not feeling

well, but become disoriented and can no longer react well enough to

exit the building or get help. Also, young children and pets may be the

first affected. The average healthy adult might not feel any symptoms

when the CO Alarm sounds. However, people with cardiac or respiratory

problems, infants, unborn babies, pregnant mothers, or elderly people

can be more quickly and severely affected by CO. If you experience

even mild symptoms of CO poisoning, consult your doctor immediately!

FINDING THE SOURCE OF CO AFTER AN ALARM

Carbon monoxide is an odorless, invisible gas, which often makes it

difficult to locate the source of CO after an alarm. These are a few of

the factors that can make it difficult to locate sources of CO:

• House well ventilated before the investigator arrives.

• Problem caused by “backdrafting.”

• Transient CO problem caused by special circumstances.

Because CO may dissipate by the time an investigator arrives, it may

be difficult to locate the source of CO. BRK Brands, Inc. shall not be

obligated to pay for any carbon monoxide investigation or service

call.

POTENTIAL SOURCES OF CO IN THE HOME

Fuel-burning appliances like: portable

heater, gas or wood burning fireplace,

gas kitchen range or cooktop, gas

clothes dryer.

Damaged or insufficient venting:

corroded or disconnected water heater

vent pipe, leaking chimney pipe or flue,

or cracked heat exchanger, blocked or

clogged chimney opening.

Improper use of appliance/device:

operating a barbecue grill or vehicle

in an enclosed area (like a garage or

screened porch).

Transient CO Problems: “transient” or on-again-off-again CO problems

can be caused by outdoor conditions and other special circumstances.

The following conditions can result in transient CO situations:

1. Excessive spillage or reverse venting of fuel appliances caused by

outdoor conditions such as:

• Wind direction and/or velocity, including high, gusty winds.

Heavy air in the vent pipes (cold/humid air with extended

periods between cycles).

• Negative pressure differential resulting from the use of exhaust

fans.

• Several appliances running at the same time competing for

limited fresh air.

• Vent pipe connections vibrating loose from clothes dryers,

furnaces, or water heaters.

• Obstructions in or unconventional vent pipe designs which can

amplify the above situations.

2. Extended operation of unvented fuel burning devices (range, oven,

fireplace).

3. Temperature inversions, which can trap exhaust close to the

ground.

4. Car idling in an open or closed attached garage, or near a home.

These conditions are dangerous because they can trap exhaust in your

home. Since these conditions can come and go, they are also hard to

recreate during a CO investigation.

HOW CAN I PROTECT MY FAMILY FROM

CO POISONING?

A CO Alarm is an excellent means of protection. It monitors the air

and sounds a loud alarm before Carbon Monoxide levels become

threatening for average, healthy adults.

A CO Alarm is not a substitute for proper maintenance of home

appliances.

To help prevent CO problems and reduce the risk of CO poisoning:

• Clean chimneys and flues yearly. Keep them free of debris,

leaves, and nests for proper air flow. Also, have a professional

check for rust and corrosion, cracks, or separations. These

conditions can prevent proper air movement and cause

backdrafting. Never “cap” or cover a chimney in any way that

would block air flow.

• Test and maintain all fuel-burning equipment annually. Many

local gas or oil companies and HVAC companies offer appliance

inspections for a nominal fee.

• Make regular visual inspections of all fuel-burning appliances.

Check appliances for excessive rust and scaling. Also check the

flame on the burner and pilot lights. The flame should be blue.

A yellow flame means fuel is not being burned completely

and CO may be present. Keep the blower door on the furnace

closed. Use vents or fans when they are available on all fuel-

burning appliances. Make sure appliances are vented to the

outside. Do not grill or barbecue indoors, or in garages or on

screen porches.

• Check for exhaust backflow from CO sources. Check the draft

hood on an operating furnace for a backdraft. Look for cracks

on furnace heat exchangers.

• Check the house or garage on the other side of shared wall.

• Keep windows and doors open slightly. If you suspect that CO

is escaping into your home, open a window or a door. Opening

windows and doors can significantly decrease CO levels.

In addition, familiarize yourself with all enclosed materials. Read

this manual in its entirety, and make sure you understand what to

do if your CO Alarm sounds.

REGULATORY INFORMATION FOR

SMOKE/CO ALARMS

REGULATORY INFORMATION FOR CO ALARMS

WHAT LEVELS OF CO CAUSE AN ALARM?

Underwriters Laboratories Inc. Standard UL2034 requires residential

CO Alarms to sound when exposed to levels of CO and exposure times

as described below. They are measured in parts per million (ppm) of

CO over time (in minutes).

UL2034 Required Alarm Points*:

• If the alarm is exposed to 400 ppm of CO, IT MUST ALARM

BETWEEN 4 and 15 MINUTES.

• If the alarm is exposed to 150 ppm of CO, IT MUST ALARM

BETWEEN 10 and 50 MINUTES.

• If the alarm is exposed to 70 ppm if CO, IT MUST ALARM

BETWEEN 60 and 240 MINUTES.

* Approximately 10% COHb exposure at levels of 10% to 95% Relative

Humidity (RH).

The unit is designed not to alarm when exposed to a constant level

of 30 ppm for 30 days.

CO Alarms are designed to alarm before there is an immediate life

threat. Since you cannot see or smell CO, never assume it’s not present.

• An exposure to 100 ppm of CO for 20 minutes may not affect

average, healthy adults, but after 4 hours the same level may cause

headaches.

• An exposure to 400 ppm of CO may cause headaches in average,

healthy adults after 35 minutes, but can cause death after 2 hours.

Standards: Underwriters Laboratories Inc. Single and Multiple Station

carbon monoxide alarms UL2034.

According to Underwriters Laboratories Inc. UL2034, Section 1-1.2:

“Carbon monoxide alarms covered by these requirements are intended

to respond to the presence of carbon monoxide from sources such as,

but not limited to, exhaust from internal-combustion engines, abnormal

operation of fuel-fired appliances, and fireplaces. CO Alarms are

intended to alarm at carbon monoxide levels below those that could

cause a loss of ability to react to the dangers of Carbon Monoxide

exposure.” This CO Alarm monitors the air at the Alarm, and is

designed to alarm before CO levels become life threatening. This

allows you precious time to leave the house and correct the problem.

This is only possible if Alarms are located, installed, and maintained

as described in this manual.

Gas Detection at Typical Temperature and Humidity Ranges: The

CO Alarm is not formulated to detect CO levels below 30 ppm typically.

UL tested for false alarm resistance to Methane (500 ppm), Butane (300

ppm), Heptane (500 ppm), Ethyl Acetate (200 ppm), Isopropyl Alcohol

(200 ppm) and Carbon Dioxide (5000 ppm). Values measure gas and

vapor concentrations in parts per million.

Audible Alarm: 85 dB minimum at 10 feet (3 meters).

Tools you will need: pencil, drill with 3/16” or 5mm drill bit,

flathead screwdriver, hammer.

•

Do not connect this unit to any other alarm or auxiliary device.

It is a single-station unit that cannot be linked to other

devices. Connecting anything else to this unit may prevent it

from working properly.

• Do not install this unit over an electrical junction box. Air

currents around junction boxes can prevent smoke from

reaching the sensing chamber and prevent the unit from

alarming. Only AC powered units are intended for installation

over junction boxes.

Mounting Hole Sets

OPTIONAL LOCKING FEATURE

The optional locking feature is designed to prevent unauthorized removal

of the alarm. It is not necessary to activate the lock in single-family

households where unauthorized alarm removal is not a concern.

Tools you will need: Needle-nose

pliers or utility knife • Standard flathead

screwdriver

The feature uses a locking pin which is

molded into the mounting bracket. Remove

locking pin by using needle-nose pliers or a

utility knife.

To permanently remove the locking pin, insert a flathead screwdriver

between the locking pin and the lock and pry the pin out of the lock.

TO LOCK THE MOUNTING BRACKET

1. Using needle-nose pliers, detach the pin

from the mounting bracket.

2. Insert the locking pin through the

hole on the back of the smoke alarm

as shown in the diagram.

3. When you attach the alarm to

the mounting bracket the locking

pin’s head will fit into a notch on the

bracket.
